WASHINGTON D.C. — The Washington Nationals announced a paid attendance of 19,195 on Friday night at Nationals Park. It’s unclear how many of those in attendance were Giants fans, but there were more than enough — especially behind the third-base dugout — to start “Let’s go Giants” chants in the lower bowl. Landen Roupp pitched six-plus shutout innings, his second straight outing of at least six frames, and the bullpen combined for three scoreless innings as San Francisco beat Washington 4-0. After walking Jung Hoo Lee on five pitches to lead off the seventh inning, Nationals starter MacKenzie Gore left the game alongside a trainer in the middle of a plate appearance against Matt Chapman due to an apparent injury. Chapman finished the plate appearance by drawing a walk against reliever Jackson Rutledge (charged to Gore), and following Wilmer Flores’ 6-4-3 double play, Willy Adames drove in Lee by sneaking a single up the middle. San Francisco expanded the lead to 2-0 when Rutledge walked Casey Schmitt, Mike Yastrzemski, and Patrick Bailey in back-to-back-to-back plate appearances, and Bailey scored Adames with his free pass with the bases loaded. The Giants had a chance to pile on, but Nationals reliever Zach Brzykcy entered for Rutledge and got Tyler Fitzgerald to hit into an inning-ending groundout. Roupp cruised through the first six innings but was pulled in the seventh after allowing a double and a walk to begin the inning. Randy Rodríguez entered for Roupp and immediately put out the fire, striking out Robert Hassell III and getting José Tena to ground into an inning-ending 6-3 double play. The Giants doubled their lead to 4-0 in the top of the eighth inning when Wilmer Flores drove in Lee with a single, tying the Cubs’ Seiya Suzuki for the most in the National League, and Chapman scored from third on a wild pitch. Following Flores’ RBI single, a group of Giants fans began to make their voices heard in the lower bowl. Erik Miller pitched a scoreless eighth inning, and Camilo Doval finished off the win with a scoreless ninth, his 19th consecutive scoreless outing.
